An object of mass 3.05 kg, moving with an initial velocity of 5.09 i m/s, collides with and sticks to an object of mass 2.34 kg with an initial velocity of -3.28 j m/s. find the final velocity of the composite object.

hypothesising or postulating

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
